Embodiment
Core concept of the present invention is: the E-RUCCH that terminal sends can not only be on main carrier, and can send on auxiliary carrier wave, and sends random access request on the corresponding carriers of access E-RUCCH; The base station receives random access request on corresponding carriers, and sends feedback information, and then completes the random access of up enhancing.Like this, on the one hand, by the access request of all frequencies in main carrier and auxiliary carrier wave shared TD-SCDMA residential quarter, can support to access more up enhancing user's number, thereby, the random access capability of up enhancing improved.On the other hand, up enhancing users all in the TD-SCDMA residential quarter both can use main carrier, also can use auxiliary carrier wave to send random access request, and the collision probability of ascending pilot frequency code is little, thereby, reduced the probability that produces random access collision and random access delay problem.
For making the purpose, technical solutions and advantages of the present invention clearer, by the following examples and with reference to accompanying drawing, the present invention is described in more detail.
The accidental access method of up enhancing in a kind of TD-SCDMA system, as shown in Figure 1, the method comprises the following steps:
Wherein, terminal selects the mode of main carrier or auxiliary carrier wave to be specially: the mode of fixedly choosing, the mode of choosing at random or the mode of choosing according to predefined probability.
Up access channel is accessed according to the ascending pilot frequency code in step 102, base station.
Wherein, the processing of described step 102 specifically comprises the following steps, as shown in Figure 2:
The up access channel that step 1021, base station judgement receive is PRACH or E-RUCCH; If after judging that up access channel is as PRACH and access, execution in step 1022; If after judging that up access channel is as E-RUCCH and access, execution in step 1023.
Here, the up access channel that in step 1021, judgement receives is that the judgment mode that PRACH or E-RUCCH adopt is specially: judge according to the ascending pilot frequency code that receives or by the residing carrier wave of ascending pilot frequency code that receives.

Accordingly, also comprise after step 1031b:
Step 104, terminal send ascending reinforced special channel (E-DCH), and send upstream data on E-DCH according to the ascending wireless resource and the schedule information that receive on E-AGCH.
The second situation, by step 1023 as can be known, the current up access channel that receive the base station is E-RUCCH, so, in step 103, corresponding random access request is the random access request of up enhancing, and the random access request of up enhancing is the initial random access request of terminal, and step 103 comprises the following steps:
After step 1032a, terminal transmission PRACH, and initiation RRC connects the request of foundation on PRACH, and the base station is returned RRC connection foundation and completed information to terminal, and is the terminal distribution Radio Resource; Afterwards, terminal enters the RRC connection status.
